Bi-amping using ACCUPHASE electronics

I am looking for opinion from the experienced audiophiles/dealers what would be a recommended combination in using Accuphase electronics for bi-amping speakers explicitly designed to be bi-amped, with a resulting significant audible benefits.
My current proposed configuration is:
Accupahse C-2410 as pre-amp.
2 x Accuphase A-45 as power amps (for either vertical or horizontal bi-amping)
Von Schweikert VR-5A speakers (4 ohms W, 8 ohms M/T)
Any suggestions/corrections to the proposed configuration?
Thanks in advance.
